8 Claims, N0 Drawings 1 POLYMERS FROM UNSATURATED CARBONATE ESTERS OF PHENOLIC COMPOUNDS This application is a continuation-in-part of copending application Ser. No. 813,316, filed on Apr. 3, 1969 now abandoned.

The most commonly known polycarbonaternaterials are generally linear polymers which are commercially advantageous because of their thermoplastic and extremely durable nature. Notwithstanding, however, linear thermoplastic polycarbonates possess some inherent disadvantages due to their melt flow properties and their lack of stability to thermal and hydrolytic degradation, particularly when employed in the presence of steam, hot water, hydrolyzing liquids and the like. Such deficiencies have prevented the use of polycarbonate materials for the preparation of articles used daily such as crockery, containers and the like and also for the preparation of surgical materials and so on.

It is therefore an object of this invention to provide a new polymeric material which is devoid of the foregoing disadvantages.

Another object of this invention is to provide a new polymeric polycarbonate material having improved melt flow properties and increased stability to thermal and hydrolytic degradation.

Still another object of this invention is to provide a synthetic material which can be thermoplastically processed and which is suitable for the production of articles which must have high resistance to hot water, steam and hydrolytic fluids.

Still another object of this invention is to provide a new polymeric material suitable for use in the production of crockery, surgical instruments, containers, as raw materials for varnishes and so on.

The foregoing objects and others are accomplished in accordance with this invention, generally speaking, by providing as a new composition of matter a polymeric compound having the statistical formula:

A H R H H t l l H will LI .n.

wherein A is hydrogen or a methyl group, X is halogen or a methyl group, Ar, is a bivalent aromatic radical which may or may not contain substituents on the nucleus such as, for example, phenylene, anaphthalene, b-naphthalene, a-anthracene,

anthracene, fluorene, phenanthrene, biphenylene, triphenylene and the like; Ar, is a monovalent aromatic radical which may or may not be substituted on the nucleus such as, for example, phenyl, naphthyl, anthryl, phenanthryl and the like; or it may be the same as Ar but having an -OH group attached to one of the arylene valences; misO or 1; n is0 or l;ois 0, l or 2;pis an integer of from about 5 to about q isl or 2; r is an integer of from about 5 to about 1,000; g is a number of from about 5 to about 200; R is hydrogenor a methyl group; R is hydrogen, halogen, lower alkyl, aryl, a carboxylic acid or ester group of'a monohydric alcohol, the amide or the nitrile group, an ester group of a monocarboxylic acid or an alkoxy group such as, for example, fluorine, chlorine, bromine, iodine, lower alkyl, preferably having from about one to about eight carbon atoms, including methyl, ethyl, propyl, butyl, pentyl, octyl as well as the corresponding cycloaliphatic radicals, aryl radicals such as those described for Ar an ester group of a monohydric alcohol, preferably those alcohols which contain from about one to about eight carbon atoms including methanol, ethanol, butanol, heptanol, octanol and the like; an ester group of a monocarboxylic acid including acetic, propionic, butyric, benzoic acid and the like; and alkoxy groups, preferably those containing from about one toabout eight carbon atoms such as, for example, methoxy, ethoxy, allyloxy, hexoxy, heptoxy and so on.

In the foregoing statistical formula the segment which repeats g number of times is prepared by copolymerizing unsaturated monomers containing substituents as defined for R and R. Thus, this segment of the polymer may be derived from a mixture of ethyleni-. cally unsaturated monomers in which case R may differ for each segment derived from each different monomer and R may or may not also vary or else it may be prepared from a single monomer which repeats a sufficient number of times to satisfy the number represented by g in which case R and R may be the same in each repeating segment. In the former case, statistical formula I may be written as follows:

wherein all of the units are as hereinbefore defined and R R R may be the same or different hydrogen, halogen, lower alkyl or aryl radicals, an ester group, the amide, the nitrile or the carboxylic acid group or an alkoxy group; 3,, S S are the same or different numbers and S 8 S,=g. The most important compounds of this invention, however, correspond to the above formula in which n and are 0 and q is 1. Thus, the preferred formula is:

wherein A is hydrogen or a methyl group;

Ar is phenylene, diphenylene naphthylene, a diphenylene alkane, a diphenylene cycloalkane, a diphenylene ether, a diphenylene sulphide, a diphenylene ketone, 21 diphenylene sulphone or di- 4-phenylene-4-diisopropylbenzene;

Ar is phenyl, halophenyl or alkylphenyl in which the halo group is chlorine or bromine and the alkyl group contains one to four carbon atoms;

R is hydrogen, halogen, methyl, phenyl, -COOH or COOR" in which r" is an alkyl group having one to eight carbon atoms, including cycloalkyl groups such as the cyclohexyl group;

R is hydrogen or a methyl group;

p is a number of from about to about 100;

g is a number of from about 5 to about 200; and

r is a number of from about 5 to about 1000.

The most preferred products are those of the above formula wherein Ar, is diphenylene-isopropylidene, di- 3 ,5-dichloro-4-phenylene-isopropylidene, l l -diphenylene cyclohexane or di-4-phenylene-4-diisopropylidenebenzene.

The new compounds of this invention can be prepared by known methods from copolymers containing free or masked hydroxyphenyl side chains and having the formula:

or, as explained for formula I,

' "f 'ff 7" l liar insis CH2 constituents with monoor bivalent phenols of the formula III wherein A, X, D, m, n, o and q are as already defined. Thus, monoand bivalent phenols such as, for example, 0-, mor p-isopropenyl-phenol, p-isopropenyl-o-cresol, 2,6-dichloro-p-isopropenyl-phenol, mor p-vinylphenol, p-vinyl-o-cresol, p-allyl-phenol, m-allyloxyphenol, 3,4-dihydroxyallyl-benzene, 2,4-dihydroxyallyl-benzene and the like, their chlorocarbonic acid or monophenyl-carbonic acid esters or the corresponding trimethyl-silane derivatives, are reacted with copolymerizable monomers of the formula (wherein R and R, are as already defined) in a molar ratio such that one part of the phenol of formula III is used to the sum of the parts of the copolymerizable monomer or mixtures thereof equal to g. Known methods may be used for effecting the copolymerization such as, for example, ionic copolymerization as described in German Pat. No. 1,153,527 or, preferably, free radical copolymerization, preferably with the use of masked phenols and especially the trimethylsilane derivatives. The last mentioned compounds are easily.

obtained by reacting the corresponding phenols with, for example, hexamethyl-disilazane or trimethylchlorosilane in the presence of acid acceptors.

In this process the preferred phenols are those of formula III wherein n and o are and q is 1. Thus, the preferred formula is:

In preparing the copolymers of formula II, the monomers which may be used as reaction partners for the unsaturated phenols include, for example, ethylene, propylene, isobutylene, vinyl chloride, vinylidene chloride, acrylic and methacrylic acid, their alkyl esters and amides, acryloand methacrylonitrile, vinyl acetate, propionate and benzoate, vinyl-methyl, -ethyl and -isobutyl ether, styrene, a-methyl-styrene, vinyltoluene, p-ethyl-styrene, 2,4-dimethyl-styrene, orthochlorostyrene, 2,5-dichlorostyrene and any of those listed in U.S. Pat. No. 3,225,119. Such compounds may be used either alone or in mixtures with one another.

Any suitable bivalent phenols may be mixed with the copolymers of formula II, including all those which are known to be suitable for the preparation of polycarbonates. Some such suitable compounds are, for example, hydroquinone, resorcinol, 4,4'-dihydroxydiphenyl, bis-(4-hydroxyphenyl)-alkanes such as bis-(4-hydroxyphenyl)-methane, l l -ethane, l l -and-2,2-propane, -l,l-and-2,2-butane and so on, 1,1-bis-(hydroxyphenyl)-cycloalkar1es, -ethers, -sulphides, -ketones, sulphones and the like as well as bisphenols which are halogenated on the nucleus, a,a'-bis-(p-hydroxyphenyl)-p-diisopropylbenzene and the like. Further examples of such suitable compounds may be found in U.S. Pat. Nos. 3,028,365; 2,999,835; 3,148,172; 3,271,368; 2,970,131; 2,991,273; 3,271,367; 3,280,078; 3,014,891; 2,999,846 and so on.

If copolymers with free hydroxyphenyl side chains or with phenylcarbonic acid ester or trimethyl-phenoxysilane side chains are to be prepared, the reaction can be carried out using diesters of carbonic acid, preferably diaryl carbonates, such as diphenyl carbonate, the cresyl carbonates, dichlorophenyl carbonates, bisphenyl carbonates of bivalent phenols and the like in a transesterification reaction at temperatures of between about 150C and about 350C. in which alkaline or acidic transesterification catalysts may be employed in the usual amounts. Such reactions are described in detail in Chemistry and Physics of Polycarbonates by Hermann Schnell and Polycarbonates by Christopher and Fox, for example. If silane copolymers are used, the reaction is virtually the same as that of the copolymers carrying side chains of free hydroxyphenyl radicals as terminal groups since the trimethyl-silane radicals are easily split off because of intersilylation.

The polycarbonate side chains can also be prepared in a known manner by using phosgene or bischlorocar- 50C. and the solvents used should be among those in which the copolymer and, preferably, also the final product are soluble. Some such suitable solvents are, for example, methylene chloride, chloroform, chlorobenzene and mixtures thereof and the like. In such solution processes, those copolymers in which the terminal groups of the side chains consist of phenylchlorocarbonic acid ester groups may also be used as well as phenol and trimethyl-phenoxy-silane copolymers.

Suitable monovalent aromatic compounds which may either be substituted or unsubstituted on their nucleus and from which the Ar terminal groups of the formula are derived include, for example, phenol, cresols, monoand dichlorophenols, p-tert.-butylphenol and any of those listed in the patents and texts cited hereinbefore.

The amount of the bivalent phenols and carbonic acid derivatives to be used per mol of the copolymer of formula Il may vary within wide limits depending upon whether shorter or longer polycarbonate side chains are desired. However, at least 1 mol of bivalent phenol and carbonic acid derivative should be used for every phenolic hydroxyl group of the copolymer so that at least one carbonate or polycarbonate chain is grafted onto every phenol group of the copolymer. The preferred amounts can easily be calculated from the numerical value of p in formula I.

As discussed hereinbefore the new polymeric compositions of this invention may contain substituents in addition to those specifically spelled out in the statistical formula. Thus, for example, any of the aromatic nuclei contained in the polymer may contain substituents as can any of the aliphatic groups. Any suitable substituent may thus be contained in the polymer but preferably those substituents which are inert to the reaction components during the production of the polymers. Some suitable substituents which may be employed include, for example, halogen atoms including fluorine, chlorine, bromine, iodine; lower alkyl radicals such as, for example, methyl, ethyl, butyl, hexyl and the like; alkoxy radicals such as, for example, methoxy, propoxy, hexoxy and the like; nitrile groups as already set forth herein; nitro groups, carboalkoxy groups such as, for example, carbomethoxy, carbobutoxy and the like; dialkyl amino groups such as, for example, dimethyl amino, dipropyl amino, methylethyl amino; mercapto; carbonyl; thiocarbonyl; phosphoryl; phosphato; siloxy and so on.

The new polymeric compounds of this invention are superior to the known linear polycarbonates due to their improved melt flow properties and their increased stability to thermal and hydrolytic degradation. Since the new polymers of this invention can be thermoplastically processed, they are particularly suitable for producing articles which must have an especially high resistance to hot water and steam as well as to fluids which cause hydrolysis upon the application of heat. Some such articles include, for example, articles used daily such as crockery, surgical instruments, containers and the like. The new polymeric compounds can also be used as raw materials for varnishes.

The invention is further illustrated but is not intended to be limited by the following examples in which all parts and percentages are by weight unless otherwise specified.
